The cable channel said Thursday that the series’ upcoming eighth season will be its last.

“Dexter” stars Michael C. Hall as a Miami Police Department blood-spatter expert who’s got his own list of murder victims. The drama debuted in 2006 and became Showtime’s first hit series, with a steady performance in the ratings through its run.

The final season begins June 30. It will feature English actress Charlotte Rampling as a neuropsychiatrist specializing in serial killers, and more of Dexter’s criminal romantic interest, Hannah, played by Yvonne Strahovski.
